Squat down, grab bars, lift, shoulder support, bow legs, clean and jerk... on the afternoon of the 8th, when the peninsula reporter came to the weightlifting training hall of the city sports school, the afternoon training class had already begun, and more than 20 female athletes were silently repeating their exercises and lifting barbells again and again. Different from the traditional impression of reporters, weightlifters are short and stout. Some of the girls here are over 1.70 meters tall. Most of them are well-proportioned, with beautiful hips and tight arms. Only a few of them are tall and stout, while the rest can't see any trace of stout. "Because China used to do weightlifting at small levels, people saw the success of 48kg and 52kg athletes, so they took it for granted that weightlifting would make people grow short, but in fact scientific practice would not affect children's height development. Just imagine, even in daily life, how tall can a person weightlifting about 100kg be? Plus muscular will appear stout, but this does not mean that all weightlifters are stout. Five or six little girls in our team are over 1.70 meters tall, and some boys are nearly 1.90 meters tall. " Liu Eryong, coach of the women's weightlifting team, told reporters that weightlifting not only did not affect the height of the children, but also did not destroy their figure. "As you can see, because of the long-term squat practice, the children's thighs and buttocks are very beautiful. Some small fat people have lost more than 10 kg in a few months and their muscle lines look better. With the deepening of scientific training, weightlifting is no longer the sport that people think destroys their bodies. "
